kamailio doesn't reply on internal interface
by Zhan Bazarov 19 Aug '19

19 Aug '19

Hello, we have interesting issue... Some time kamailio comes unreachable on private interface for asterisk, but port checked via telnet and everything is ok... ps. connection via public ip works good root@kamailio:/usr/local/etc/kamailio# lsof -i :5068 | grep LISTEN kamailio 6014 root 13u IPv4 8341589 0t0 TCP kamailio.local.ip:5068 (LISTEN) kamailio 6014 root 14u IPv4 8341590 0t0 TCP kamailio.public.ip:5068 (LISTEN) root@kamailio:/usr/local/etc/kamailio# telnet from asterisk machine: root@asterisk:/etc/asterisk# telnet kamailio.local.ip 5068 Trying kamailio.local.ip... Connected to kamailio.local.ip. Escape character is '^]'. But peer is unreachable in asterisk... More than, kamailio comes reachable when I change transport from TCP to UDP, or when I restart kamailio daemon(but it situation repeats every day).. Any ideas how I can fix it? thanks!

set_rtpengine_set(set1, set2) issue
by Juha Heinanen 19 Aug '19

19 Aug '19

My sip proxy has two rtpengine sets: # sip-proxy_ctl rtpengine.show all { url: udp:192.26.134.1:6050 set: 0 index: 0 weight: 1 disabled: 0 recheck_ticks: 0 } { url: udp:192.26.134.40:6050 set: 1 index: 1 weight: 1 disabled: 0 recheck_ticks: 0 } Config makes callBefore calling rtpengine_offer(), config calls set_rtpengine_set("1", "0"); rtpengine_offer("..."); As result, debug shows that sip proxy sends TWO offer commands to the rtpproxy in set 1 and NONE to the rtpproxy in set 0. Debug at set 1 engine: Aug 19 18:06:08 buster-10-0 rtpengine[1314]: NOTICE: [5e1407211cc50fd9]: Creating new call Aug 19 18:06:08 buster-10-0 rtpengine[1314]: INFO: [5e1407211cc50fd9]: Replying to 'offer' from 192.26.134.1:33284 (elapsed time 0.000812 sec) Aug 19 18:06:08 buster-10-0 rtpengine[1314]: INFO: [5e1407211cc50fd9]: Received command 'offer' from 192.26.134.1:33284 Aug 19 18:06:08 buster-10-0 rtpengine[1314]: INFO: [5e1407211cc50fd9]: Replying to 'offer' from 192.26.134.1:33284 (elapsed time 0.005247 sec) I haven't been able to figure out, why that is the case. It is a bug, or am I missing something? I added INFO call to set_rtpengine_set_f(): INFO("set1/set2 = %u/%u\n", selected_rtpp_set_1->id_set, selected_rtpp_set_2->id_set); return 1; and it correctly printed: Aug 19 18:06:08 salmon /usr/bin/sip-proxy[26911]: INFO: rtpengine [rtpengine.c:3574]: set_rtpengine_set_f(): set1/set2 = 1/0 Any ideas? -- Juha

Hello everyone, I need to setup Music on hold feature and I did all modifications in configuration file and did all steps for setup: 1- load MOH and all requirement modules . 2- rtpproxy setups and works correctly 3- mohqueue and mohqcalls tables created. 4- audio file with type index (novanet.8) exists 5- parameters of MOH module setup and mohq_process() function called in request_route()‌. 6- table mohqueue initiated like this‌: +----+------+----------------------------+-------------------+---------+-------+ | id | name | uri | mohdir | mohfile | debug | +----+------+----------------------------+-------------------+---------+-------+ | 1 | main | sip:main at 191.38.245.2 | /var/kamailio/MOH | novanet | 1 | +----+------+----------------------------+-------------------+---------+-------+ Kamailio starts successfully and no error appears , call setup but on hold doesn't work and no audio file plays. I review all previous mailing lists responses but no one answers completely and before me others had this problem.

Replacing Caller ID
by Pete Kay 18 Aug '19

18 Aug '19

Hi Could anyone tell me if there is a module for replacing the caller ID in the SIP messages? I need to replace the caller ID when the call comes in and leaves Kamailio. When the egress sends back any response, I need to revert the caller ID back to its normal form. I have a long list of numbers to be used as caller-ID, and I need to keep modifying them without having to restart Kamailio. Do I need to write my own modules for maintaining the list of numbers to be used as caller-id? I am running at 2000 CPS, so I think I need to implement some sort of hash table in order for the caller id to be retrieved in round roubin fashion very quickly. Is there any modules for this purpose or I need to write a cusom one? Pete

Re: [SR-Users] Wildcarded IMPU
by Henning Westerholt 17 Aug '19

Hello Maryam, (please keep the list in CC) understand. There is work ongoing to update the IMS modules (e.g. refer to https://www.kamailio.org/wiki/features/new-in-devel). I don't know about a current effort to add wildcarded AVPs to them, though. If you like to implement something in this regards, it is always good to announce it quickly on the developer list sr-dev to get some feedback and to to synchronize with other developers. Cheers, Henning Am 17.08.19 um 08:04 schrieb Maryam Baghdadi: Hello Henning, Thank you for your response . I read all ETSI‌ standards , latest version of standards are according to Release15 IMS but IMS modules in kamailio support Release 7 IMS. for example there is Wildcarded_IMPU AVP in AUR in R15 IMS which isn't implemented in IMS_icscf module in kamailio . I know all AVP lists are exist in kamailio and I can add my requirements to modules code . I just wanted to know ims modules in kamailio will be updated or not?

uac_replace_from() and multiple branches
by John Quick 16 Aug '19

16 Aug '19

v5.2.3 of Kamailio. Serial forking is used to route calls to a multiple destinations as described in documentation for the TM module. Also using the DIALOG module - my script calls dlg_manage() before loading the serialised branches. I need to be able to substitute the username part of the From header and have been trying this with calls to uac_replace_from(). modparam("uac", "restore_mode", "auto") modparam("uac", "restore_dlg", 1) There is no problem if all branches use one substituted From username, in which case my script calls uac_replace_from() in the main route. uac_replace_from("sip:" + $avp(route:src) + "@" + $fd); However, I may need to substitute a different value for each branch. Can this be done? I tried moving the call to uac_replace_from() into the branch route, but then I get an error when the final BYE is received: ERROR: uac [replace.c:281]: replace_uri(): decline FROM replacing in sequential request in auto mode (has TO tag) Is there a simple solution to this please? Hoping I can still use UAC auto restore mode because manual restore looks quite tedious/complex. Thanks. John Quick Smartvox Limited www.smartvox.co.uk

I read documentation for pike usage.. and have a doub.. what it's the best for very dinamyc ip of my devices.. i mean, i'm just curious of that very ironic and problematic scenario: for the scanners i setup fail2ban but only when the scaning are detecte.. but if i have the pike option how this: # this it's my setup for pike due the dinamyc ip and devices over the internet: modparam("pike", "sampling_time_unit", 4) modparam("pike", "reqs_density_per_unit", 80) modparam("pike", "remove_latency", 60) ... route { if (!pike_check_req()) { xlog("L_ALERT","ALERT: pike block $rm from $fu (IP:$si:$sp)\n"); exit; } ... } I put the remove latency in 60, so then due are dinamycally must remian in memory more (due any one will be a possible clilent), just ban if there are 180 (60*3) request each 4 seconds, it's a good configuration or maybe i'm wrong please help me! -- Lenz McKAY Gerardo (PICCORO) http://qgqlochekone.blogspot.com

RFC 3860 support - Kamailio is sending SUBSCRIBE back with extra Via header
by Praveen Vatti 15 Aug '19

15 Aug '19

Hi Kamailio support, Basically, I am looking for RFC3860 support - i.e., accept SUBSCRIBE for reg event and send 200OK, NOTIFY to client. With some browsing on Internet I came across Kamailio, which is supporting RFC3860. I have installed and attached is my CFG file. I am sending a SUBSCRIBE request with reg event to Kamailio and it is sending back the same request with extra Via header. Via now contains Kamailio system IP and the source of SUBSCRIBE IP. Please help me in resolving this issue. I have loaded db_mysql, dialplan, tm, sl, presence, presence_reginfo modules. Thanks, Praveen

Uac_replace for header's parameters
by Duarte Rocha 14 Aug '19

14 Aug '19

Greetings, I'm using uac_replace_to() and uac_replace_from() to do some number manipulations. It allows me to modify and automatically restore Display Number and URI. This works nicely, however it only allows to manipulate URI's parameter. Is there any method to the same and include the Header's parameters too? Best regards, Duarte Rocha
